| Abstract | Tween 80$^{®}$ is a surfactant widely employed to enhance remediation of contaminated soils. Actually, there are few convenient and selective methods to quantify Tween 80$^{®}$ at low concentrations. Here, we report a new and simple quantification method to monitor Tween 80$^{®}$ analysis. Our method is based on the enhancement of the fluorescence of 6-(p-toluidino)naphthalene-2-sulfonic acid (TNS) by formation of micelles with Tween 80$^{®}$. Results show a linear calibration curve with a correlation coefficient R $^{2}$ of 0.99, a detection limit of 0.13 mM and a quantification limit of 0.19 mM. This method showed better performances compared to actual methods such as UV absorbance and total organic carbon measurements. In addition, we demonstrated that the measurements using this new technique are impacted only at 3.5 % maximum by the presence of oxidation by-products formed during oxidation of Tween 80$^{®}$ by the electro-Fenton process or by hydrophobic organic contaminants present in solution. Fluorescence measurements of soil washing solution with real contaminated soil show almost no impact on Tween 80$^{®}$–TNS micelle analysis. The analytical method proposed for Tween 80$^{®}$ analysis could replace the currently used conventional method because it is quite simple, highly sensitive and more selective. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
